Loox,

To all whom t may'concem:

Be it known that I JOHN DQIIESSLER, a citizen of the United States, residing at Villa Grove, in the county of Douglas and State of Illinois, have invented new and useful Improvements in Locks, 0f which the following is a specification.

This invention comprehends improvements in anautomatic lock primarly intended for the locking of doors of toiletrooms upon railway cars when the train is approaching a station and automatically effecting4 the un# locking action of the door when the trainis leaving a station. i c c The primary object of the invention is the provision of a device of the above stated character which is simple `in ,c construction, durable and eflicient in use, and one wherein the operation thereof is controllablefrom the trap doors of a railway car,`but while thc inventionis particularly adaptable for railway cars, itwill be evident that thesame may be employed on any type of-"vehicle found desirable and convenient for use. With the above and other objects in view, the invention consists in the novel features, details of construction and combination of parts which will hereinafter be more fully set forth, illustrated in the accompanying drawings and pointed `out in theappended claims.

In the drawings: Figure 1 is a diagrammatic plan view; Fig. 2 is a longitudinal sectionalview; Fig` 3 is a'transversesectional view; and Figs. 4 and 5 are detail views of the lock construction.` c c Referring more particularly to the accompanying drawings, wherein like characters of reference refer to corresponding parts `in the several views, 5 denotes theflooring of a passenger coach provided withthe usual toilet rooms 6, vestibules 7 and `trap` doors 8 swingingly positioned inthe vestibules for vertical movement. l ,l

Secured to the under surface ofthe c car flooring 5 andV depending therefrom are hangers 9 in which are journaled shafts 10 disposedlengthwise of the flooring and in spaced parallelism one to the other, andfor c the sake of clearness` these shafts will be hereinafter referred to as main operating shafts. The trap doors hereinbefore referred to, constitute four in number and a pair of each of the doors is locked in each of the vestibules at opposite "ends "of the o Specification of Letters Patent.

cars and theLchiefcharacteristic offtheinvention residesjina novel means for operatively connecting the main operatin shafts with these trap doors, whereby as t e train 1s approaching a station the swinging of the said doorsto `avertical `position will lock the doors 11 leading into each of the toilet rooms 6,` andl obviously when the train is leaving `a` station the swinging ,of the trap doors toassume a horizontal position by the traincrew will tend to unlock the doors 11 `inorder that these rooms may `be `accessible to the publie,` c n In carryingout these objects, useis made ofla bracket arm 12having one end rigidly connected `to the bottom edge of eachgate ortrap door 8 and"depending therefrom, while keyed or otherwise" suitably connected to the oppositeends ofthe main operating shaft 10 and `projecting at riwht angles with respect to the link 12, as aftioperating 1* crank i arm 13. `Suitably supported on the bottom of the floor I5 at a pointbetween the main operating shaft and trap i, door, (is a pulley Mover which is .trained a flexible connection` 15 connected at one end with f thefree end of thebracket arm 12 `and at its. `opposite end with the shaft operating crank arm 13.` Manifestly, when the gates or trap doors 8 are swung in a vertical plane,

a pull will be` exerted on the flexible connecc w tion 1:5`and which inturn will rock the main operating shaft `10 and pull the same against the tension of the spring 16. The function accomplished by this `operation will cause the"` keeper plate 17 tof slide over the `latch bolt" 18 "and accomplish the" locking action of the door 11 to `parties in the train. The lock operating mechanism comprises an auxiliaryshaft 19 rotatably journaled inbearings2)"`and`arranged`vertically with respect c to thecar floor.` Carried bythe main `operating shaft 1()"and projecting in an out` ward lateral direction is an arm 21 universallyconnectedwith a second armg22 on the auxiliary shaft`19, by the link23. That is to` say, by this` form of construction and upon he"`rocking"of the main operating shaft 10, througliythe medium of the link 23, `will rotate the auxiliary shaft 19 in its bearing 20, and this action will" in turn rotategthe; pinion 24 keyed `on the upper end `of the `auxiliary shaft 19"an`d mounted vertic/ally inl thebearings l25 of the casing 126;

In the inturned flanged guides 27 of said 'l plata slidably mounted the keeper `plate 17, and due tothe rotation of the pinion 24 will cause'the same to mesh with the rack 17 on the inner face ofthe keeper plate 17, and move the latter over and into obstructing relation with respect to the latch bolt 18, preventing the entrance to the toilet rooms while the trainis approaching or at ter 29,1while. theo-pposite end of the spring is connected .with an arm 30 keyed or otherwise. suitably secured to the main operating shaft 10,. Aand the purpose of this spring is to automatically rock the main operating y shaft 10 when the gates are loweredto a horizon-tal position, causing a reverse rotation of .the pin 24,. and a reverse sliding movement ,of the keeperplate 17, whereby the door 11 is in aV released or unlocked position- .From the foregoing description,v taken in .connection with the accompanying drawings,.. the. advantages of. construction and the method of Voperation will be readily apy parentto those. skilled in the. art to which the invention relates, and. while I` have described the. principles of operation of the invention, together withtheV device which I new consider tol be the best embodiment thereof., I desire to have it understood that the device. shown-is merely illustra-tive and that such. changes may be made when desired as. are 'within the scope of the appended claims..

What claimedas new, is

y1. The combination. with-a vehicle, doors located interiorly of the vehicle, swinging members arranged exteriorly ofthe vehicle, door locking. mechanism, means for connecting the door locking mechanismy with .the swing-ing members for effecting. the lock.- ing action of the doors upon the swinging .of the members' in one direction,` and rotatablemeans for automatically throwing the door locking mechanism to a released posi.- tionupon the lifting; of the swinging members in anopposite direction..

2. Aena-automatic locking'device compris'- ing in. combination with a plurality of swingingmembers, a mainV operating shaft, aconnection. between thel main operating shaft and-eachr of said. swinging members, and means operatively connected with the main operating shaft for locking` the doors upon: movement of' the,y members in one direction and releasing the lock when the swinging members are moved in the opposite direction.

8. The combination with a vehicle, doors therefor, a lock for each door and means for operating said lock, said means comprising an operating shaft, an auxiliary rotatable shaft having connection with the operating shaft, a slidable member, rotatable means carried by the auxiliary shaft for moving the. slidable member.

4.. In combination with a vehicle, doors therefor, a plurality of swinging members arranged at the opposite ends of the vehicle, a main operating shaft journaled beneath the vehicle, a flexible connection connecting the main operating shaft with each swinging member, an auxiliary shaft, a connectionV between the main operating shaft and the auxiliary shaft for imparting to the latter a rota-ry movementl upon the operation of the swi-ngingmembers in one direction, a locking member, and. means carried by the auxiliary shaft and coperating with the operating member for operating the locking member.

5.. A door locking mechanism for vehicles comprising a. main operating shaft journaled lengthwise of the vehicle for oscillating movement, manually operating means having connection with the main operating shafts for moving the same in one direction, an' auxiliary shaft journal'ed in the flooring of the vehicle and disposed at an angle with respect to the main operating shaft, a connection. between the main operating shaft and the auxiliary operating shaft for imparting to the latter rotary movement, a keeper plate, andl means on the auxiliary shaft and coperating with the keeper plate for imparting to the latter a sliding movement.I
